N 0 Drawing.

To all whom it may concern:

Be it known that I, EDGAR W. SNYDER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Sized Yarn or Thread, of which the following is a specification.

This invention relates to sizing yarn or thread and has particular reference to the application of yarn or thread to ocotillo gum or a composition containing ocotillo um. g I have discovered that ocotillo gum when employed as, or an ingredient of, a composition for sizing yarn or thread produces a sized product of unusual strength.

The ocotillo plant (Fougm'em'a splendens) is a small tree which grows in considerable abundance in Northern Mexico, along the Rio Grande and elsewhere. The bark of this plant or tree contains a gum which can be extracted by the use of suitable solvents, such as gasolene, benzin, alcohol, ether, and the like, preferably in the presence of approximately from one to three per cent., of lime or magnesia, the gum being subsequently separated from the solvent by evaporation or distillation. In the use of ocotillo gum in the practice of my invention, I preferably melt the gum Application filed August 9, 1917. Serial No. 185,347.

proportion of other sizing materials such as waxes.

The ocotillo gum or sizing material containing ocotillo gum, may be advantageously applied to the yarn or thread by means of sizing machines of the character now generally in use.

The quantity of my improved sizing material to be applied to the yarn or thread Will depend upon the use to which the sized material is to be put as will be readily understood by those skilled in the art.

While I have described in detail the preferred practice of my process it is to be understood that I am not restricted to the details of procedure except as set forth in the appended claims.

Having thus described my invention, I claim:

1. The herein described product comprising yarn or thread having a sizing comprising ocotillo gum.

2. The herein described product compris- EDGAR W. SNYDER.
